NEW YORK, Oct 9 (Reuters) - Oil prices rose more than 1percent on Tuesday, after two sessions with lower settlements,as the threat of supply disruption in a tense Middle Eastcountered concerns about slower growth and resulting sluggishdemand for oil.

NATO said on Tuesday it had drawn up plans to defend Turkeyif necessary against any further spillover of violence fromSyria's border areas where rebels and government forces arefighting for control.

"It's a political risk premium coming into the market now,not really supported by fundamental data," said Andy Sommer, oilmarket analyst with EGL in Switzerland.

"If you look at the demand side, prices should be a bitlower than they are currently. But the risk, or fear, that thisTurkey-Syria conflict might spread further in the Arab world isincreasing that risk premium."

The turmoil in Syria has reinforced the concerns aboutsupply security already raised by the ongoing dispute betweenIran and Israel and the West over Tehran's controversial nuclearprogram.

The dispute over the nuclear issue has led to tough U.S.-ledsanctions on Iran and a European Union (EU) ban on importingIranian crude.

U.S. RBOB gasoline futures jumped 2 percent duringTuesday's session, continuing to be lifted by tight gasolinesupply in the U.S. East Coast region combined with seasonal andunplanned work curbing refinery capacity utilization.

Brent November crude rose $1.33 to $113.15 a barrelby 11:25 a.m. EDT (1525 GMT), having reached $113.99.

The price increase pushed Brent back above the 200-daymoving average of $112.18 and the 50-day moving average of$112.68, key technical levels watched by chart-watching traders.

U.S. November crude was up $1.64 at $90.97 a barrel,after reaching $91.04 and moving back above the 100-day movingaverage of $89.86.

Brent's premium to U.S. crude increased, movingabove $23 a barrel intraday, as delays in the October loading ofNorth Sea Forties cargoes and the Middle East uncertainties havehelped push Brent's premium to its highest since October 2011.

The geopolitical tensions countered concerns about slowingeconomic growth reinforced when the International Monetary Fundcut its global growth forecast for the second time since Apriland warned U.S. and European policymakers that failure to fixtheir economic ills would prolong the slump.

Oil prices also were tempered during Tuesday's session whenSaudi Arabia reiterated its intention to keep high oil pricesfrom harming a sputtering global economy.

OPEC's biggest oil producer is likely to continue pumpingcrude at a 30-year high around 10 million barrels per day(bpd)through October, Saudi Oil Minister Ali al-Naimi said onTuesday, helping compensate for the cut in exports fromsanctions-hampered Iran.

Naimi said oil prices were still too high and Riyadh wouldlike Brent to fall closer to $100 a barrel.

More supply is also on the way from neighboring Iraq, OPEC'ssecond-biggest producer after Saudi. Exports this month areexpected to rise above 2.8 million bpd, the highest in decades,and efforts are underway to more than double output by 2020.
